LOVE this look of these and gold shelves if I can modify to create something that works for my book space in our --- Cup Half Full: Rustic Wood Shelf DIY [using Ikea EKBY LERBERG brackets painted gold, and gray stained shelves]

Your playroom shelves are similar to these but not as big/sturdy. These come in multiple colors and we can even put feet on them to make them more "official" furniture looking to fit into the room better. We'd also make super cute labels for the bins.
